iOS 6 unveiling confirmed by WWDC signage

It was hardly a mystery at this point, but the cat is now officially out of the bag: Apple will unveil iOS 6 at its annual Worldwide Developer Conference next week. Instagram user Zac Altman on Friday posted a photo of workers hanging signage at the show, and “iOS 6” can be seen quite clearly in the image above. We’ve already shared our thoughts on what might be coming in the next major release of Apple’s mobile OS, and Apple will shed light on exactly what we can expect from iOS 6 during its keynote, which is set to begin at 1:00 p.m. Eastern, 10:00 a.m. Pacific on Monday.
